Summary of Charge Controller Range


SEC UK MPPT Charge Controllers

MPPT; Max Power Point Tracking is an efficient way of transferring power from the solar array to the energy storage system. As the amount of sunlight varies, the PV panel and battery’s characteristics will change. An MPPT will optimise the charging profile from the PV array to the batteries, ensuring maximum power transfer can be achieved, this is called the Maximum Power Point. The MPPT uses this process to find the most efficient charging point for the system. MPPT solves the problem of choosing the best load to solar panel in order to get the most usable power.

SEC UK PWM Charge Controllers

A PVM Charge Controller is an efficient solar charge controller that adopts the most advanced digital techniques. The multiple load control modes enable it to be widely used on solar home systems, traffic signals, solar street lights and solar garden lamps.

Pulse-width modulation PWM, or pulse-duration modulation, is a technique used to encode a message into a pulsing signal. The main advantage of PWM is that power required by the unit (the power load) is very low. When switched off there is practically no current being drawn, when it is switched on and power is being transferred from the PV array, there is almost no voltage drop across the PWM device.

PWM regulates the input voltage to the battery by using pulse width modulation to drop the output voltage of the PV Panel to a working 13.8 volts.
